This is a great app! It provides a lot of useful information for making your store more optimized for sales and easier to use for the customer. There could be a bit more information provided, but its pretty good for being free!!
We used this app to check our SEO score for our online store selling English wines. It's so easy to use and tells you which areas to work on, though it could be a bit more clear about how to correct the problem areas, still good!
